BELT-GUIDE.

SPECIFICATION forming part of Letters Patent No. 320,810, dated June 23, 1885.

Application filed October ll 1894.

[5 The object of our improvement is to provide such a guide which can be readily adjusted I to guide the belt in different situations, or from either side of the thrasher, all as hereinafter described.

The accompanying drawings illustrate our invention.

Figure 1 represents a side elevation of our device. Fig. 2 is a front elevation of the same. Fig. 3 is a side elevation showingthc application of our device to a belt connecting a thrasher and a straw-stacker.

Ais a standard adapted to be bolted or otherwise secured to the under side of the thrasher straw-carrier b, as shown in Fig. 3. The lower end of said standard is enlarged to form on one side a broad circular bearing for a bracket, 0, which is adapted to turn on said standard in a plane parallel with the side of the straw-carrier, said bracket being clamped in position by a bolt, cl, which also forms the pivot on which the bracket turns.

To the upper end of the face of bracket 0, at a right angle to the bearing on standard a, is secured, so as to be adjustable in a plane parallel with said face of the bracket, an arm, c, which is held in place by the pivotal bolt f.

* To the outer end of arm is secured a short I shaft, g, also adjustable in thczsame plane as 5 the arm, and secured thereto by the pivotal bolt h. A grooved pulley, 1', turns freely on shaft To the lower end of bracket 0 is adj usta-bly secured by a pivotal bolt, 00, a shaft, k, and a bracket, Z, said shaft and bracket Z being formed in one piece so that they maintain the same relative position. A pulley, j, turns freely on shaft k.

(No model.)

For the purpose of compensating for the expansion and contraction of the rope beltm, a binder-pulley, a, is mounted inthe forked free end of an arm, 0, which is hinged to the bracket Z, as shown.

1; is a grooved pulley designed to act as a driving-pulley to carry belt m, and by the use of our improved belt'guide we avoid the ne ccssity of removing one of the shafts forming part of the thrasher mechanism to fix said pul' ley on said shaft opposite the guiding-pulleys s t on the straw-stacker, as has heretofore 6; been the practice, but we secure said pulley to the outer end of said shaft, or to the arms of an outside pulley, r.

In operation belt at is passed round pulley p and over pulleys i and 7','and from thence O tothe driving-pulley a on the stacker, pass ing under the guide-pulleys s t, which are opposite the center of the thrasher straw-carrier, as fully explained in Letters Patent granted to us April 1, 188-1, No. 295,932. Bracketc is now adjusted and secured so that its face,to which the shafts r and 7c are secured is at substantially a right angle with the line of the belt. Shafts gand k are now set so that their respective pulleys will turn in planes corresponding to So the angles formed by the belt passing from the pulley r to pulleys o and to, so that the belt will run easily over them to the said pulleys. Arm 6 permits the necessary outward adjustment of shaft g.- Binding-pulley nis now caused to rest on the lower or slack side of the belt, and it is ready to run.

\Ve claim as our invention 1. The beltguide consisting of the standard a, bracket 0, arm c, shafts g and It, bolts 0 d, f, h, and 0c, and pulleys i and j, all combined in the manner specified.

2. The combination, with a belt-guide, a binder-pulley, and an arm carrying said pulley, of a bracket formed integral with one of 5 the shafts of said belt-guide, and forming a hinged support for said arm, substantially as and for the purpose specified.
